Are there any mods that have to be made to use 1.6 ratio rockers with Vortec heads like you have to do on the older heads? I'm going to run a Ramjet 350 cam in my engine(already have it) and GM uses 1.6 rollers with this cam, according to the GM parts catalog. I know the Ramjet uses Vortec based heads.

Also, has anyone used Scorpion brand rockers? They have a narrow, self-aligning rocker for a decent price.

Thanks

Mike
